Frequently Asked Questions

1. Who is NADclinic and why do you sell their supplements?
NADclinic is a clinically-led longevity brand specialising in science-backed supplements for healthy ageing. Intuisse is a topical Active NAD+ skincare brand. Through our retail partnership, the full NADclinic Optima Max supplement range is available here at Intuisse — designed to work together with our skincare for a complete inside-out approach to cellular health and visible ageing.

2. How do I choose the right supplement for me?
It depends on what you’re trying to support:If you’re new to longevity supplementation, most customers start with Enhanced Optima Max and Omega-3 PRO, then layer in additional actives based on their goals.

3. Can I take multiple supplements together?
Yes — the NADclinic Optima Max range is designed to be stacked. Each product targets a different cellular pathway, and many work synergistically. Common starter stacks include:
  • Foundational Longevity Stack: Enhanced Optima Max + Spermidine + Omega-3 PRO.
  • Cognitive Performance Stack: NR+ Neuro Optimiser + Magnesium + NAD+ Brain Booster Spray.
  • Metabolic Stack: Berberine + GlyNAC + Ca-AKG.
For specific combination questions, the FAQ on each product page outlines its strongest pairings. If you are taking prescription medication or managing a medical condition, consult a healthcare professional before combining multiple supplements.

4. How do NADclinic supplements work with Intuisse skincare?
NADclinic supplements and Intuisse Active NAD+ skincare are designed to work together as part of a complete inside-out approach to cellular health and visible ageing.

From within, NADclinic supplements support NAD+ levels, cellular energy, mitochondrial function and longevity pathways across the entire body.

At the surface, Intuisse Active NAD+ skincare delivers NAD+ directly into the skin, supporting collagen, laminin and elastin production where it’s visible.

The combination addresses skin health both at the cellular foundation and at the surface where results are seen.

5. When will I see results?
Results vary by product and by what you’re measuring:
  • Energy, focus and vitality — most users notice improvements within 2 to 4 weeks of consistent daily use.
  • Sleep and stress resilience — adaptogens like Ashwagandha typically show benefits within 2 to 4 weeks.
  • Visible skin, hair and joint changes — collagen and longevity actives typically show results within 4 to 8 weeks.
  • Long-term cellular health and healthy ageing — benefits accumulate over months of consistent intake. These supplements are a long-term investment in cellular health, not a quick fix.
Consistency matters more than intensity. Daily use over weeks and months delivers the strongest results.

6. Are the supplements clean, vegan and third-party tested?
NADclinic Optima Max supplements are formulated to pharmaceutical standards with a focus on purity, transparency and clinically meaningful doses. Specific certifications vary by product — check the individual product page for full ingredient and certification details. Where applicable, the range is free from unnecessary additives, and most products are suitable for vegan and clean-label routines.

7. How does shipping work for supplements?
NADclinic supplements are fulfilled and shipped directly by NADclinic, while Intuisse skincare is fulfilled by Intuisse. This means if you order both supplements and skincare in the same order, they will arrive in separate shipments and may be delivered at different times.

Delivery times and customs requirements vary by destination — full shipping information is available at checkout.
